I was very disappointed in this article. What about providing a strategy to help family doctors actually TREAT patients with Covid 19. This would be much more empowering, provide hope for patients and practitioners alike, and would actually turn this pandemic around. All that has been learned about early Out patient Rx of Covid 19 could be a valuable teaching platform. I'm still waiting for my peers to wake up and start acting like the physicians we were trained to be.
Athletic heart is a disease. Yes it may be conditioning to the body's requirements but it is not normal. Either extreme in everything is detrimental to health. To be an olympian athlete or to be a "couch potato" are both harmful to long term health. With extreme exercise all the muscles in the body become very fit and when the individual is not doing extreme exercise, they put less demand on the heart, therefore the heart beats slower. When the heart beats slower the diastolic time is increased, but blood coming back to the heart does not stop. Therefore the heart has to enlarge to accommodate the large volume. The increased radius also increases the tension on the wall of the chamber (Laplace's law T=Pxr2/2h). The LV does not like high tension and increases wall thickness to minimize tension. 2h is 2x wall thickness that is in the denominator. But unfortunately increased wall thickness decreases the compliance, thus the pressures have to go up to fill the heart. That is disease and may eventually lead to arrhythmias, pulmonary hypertension and/or heart failure if the pressure goes high enough. Later in life when the individual for whatever reason no longer exercise the LVH may regress to some degree. But as the LV hypertrophies along with the myocites fibroblasts also increase and when the myocites regress the fibrous tissue remains, thus the individual now has a fibrotic heart. Moderation in everything should be the norm.

Is desmopressin 0.25 mcg equivalent to DDAVP MELT 240Mg
these were well outlined
Educational, practical, enjoyable
Eddy Merckx was known to have large heart helping him win on the road. His ECG surprised many. He is still riding a bike I read at age 75.
I fully agree with Dr. Sivaciyan. Moderation in every aspect of our lives certainly leads to better outcomes.
